SPECIFICATION forming part of Letters Patent N o. 597,960, dated January25, 1898.

l y Application filed May 5, 1897. Serial No. 635,196. (No model.)

To @ZZ whom t may concern:

Be it known that I, HARRIET J. DELZELL, a citizen of the United States,residing at Jackson, in the county of Amador and State ot' California,have invented a new and useful Miners Lantern, of which the following isa specification.v

This invention relates to miners lanterns, and the object is to providea lantern which will give a stronglight and which may be used in thewettest mines and in the strongest drafts Without liability of beingextinguished.

l/Vith these and other ends in view my invention consists in a lanternembodying the several details of construction and combination of partshereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure l is a perspective View of a lantern. made inaccordance with my invention. Fig. 2 is a vertical longitudinal section.Fig. 3 is a vertical transverse section on the line :c os of Fig. 1.Fig. 4 isan end view.

Similarreference-numerals indicatesimilar parts in the several igures.

The main body of the lantern is indicated by 1 and is ofconico-cylindrical form Vwith its large end toward the front ot thelantern. This body is provided with apertures 2 and 3 at oppositepoint-s in its periphery and substantially midway of its length, thelower aperture 2 being larger than the upper one 3. A tube 4 is fittedinto the aperture 2 and is provided with a flaring lower end 5, whichforms one of the base-supports of the lantern. At the junction of theflaring end 5 with the tube e an internal annular flan ge 6 is formed,with which the spring-actuated hook-catches 7 on the reservoir 8 of thelamp 9 are adapted to engage in order to support the lamp Within thetube a, with its burner projecting into the lantern-body. Instead of alamp a suitable holder for a candle may be similarly supported withinthe tube l. The hook-catches 7 are preferably of spring metal, and inorder to increase 'their spring action to insure positive engagementwith the flange 6 Va spring-wire 10 is secured midway of its length tothe lamp-reservoir, with its free ends engaging the inner faces of thehook-catches 7. The ends 11 of the spring-catches project bemay bedisengaged in order that the lamp may be removed. K

The aperture 3 is for the purpose of ventilating thev lamp, and a shorttube 12 is secured in this aperture. A cap 13 is fitted over the upperend of the tube in such manner as to leave a space 111- between them topermit ventilation of the lantern and at the same timeexclude Water andstrong currents of air from it.

15 represents a reflector arranged in the rear of the lantern andpreferably of a diameter to lit the interior of the lantern-body. Thereflector maybe permanently secured to the lantern-body, but ispreferably detachably connected to it in any suitable manner. In thedrawings I have illustrated one method of attachment, consisting of ametal strip 16, iirmly secured to the back of the reiiector and bent atan angle, with its free end 17 extending beneath a strap 1S, the latterbeing secured to the lantern-body. The rear end of the lantern-body isclosed by acap 19, which is hinged to the lantern-body at 2O and lockedin its closed position by a spring-hook 21. The cap 19 may, however, bedetachably connected to the lantern-body in any other suitable manner.

To the front end of the lantern-body a tapering cylindrical rim 22 ishinged, preferably in such manner that a space 23 is left between them,and a series of shouldered stops 2e are secured tothe frontend of thelanternbody to engage the rear end of the rim 22 to limit the inwardmovement of the latter.

25 represents a spring-hook attached to the lower portion of thelantern-body and adapted to engage a projection 26 on the rim 22 to lockthe latter in its closed position. The cap 19 and the rim 22 are eachprovided with a projection 26, so disposed that it will be engaged bythe forelinger of the right hand While the thumb engages thespring-hook, and by pressing in opposite directions with the thumb andnger, respectively, the cap or rim may be quickly and easily disengagedfrom the hook.

The small end of the rim 22 is preferably somewhat larger than the largeend of the lantern-body, although they may be of the IOO same size, andthe large end of the rim 22 supports a lens 27. Instead of a lens aplain glass may be employed.

The lantern thus tapers from its front to its rear end, and any strongdraft that may move toward the front of the lantern will be carried overthe space 23, and should any draft moving toward the rear of the lanternenter the space 23 it will not affect-the burning of the lamp, since thetube 4 will protect Y the lower portion of the space 23 against a reardraft, and any current of air that enters through the upper portion ofthe space 23 will be deflected out again at the lower port-ion. Y

A wire loop 28 is. rigidly secured to the lower portion of the rim 22and projects downwardly to a level with the flaring bottom 5 of the tube4 and serves as another base-support for the lantern. The front end ofthe lantern is much heavier than the rear end, and the support 26prevents the lantern from tilting forward. The loop 28 also serves as ahandle for moving the rim 22.

One side of the lantern-body is provided with an aperture 29 to giveaccess to the wick in order to light it.

30 represents a slide supported and movable in suitable ways 3l to coveror uncover the aperture 29.

The lantern is provided with a bail 32, and the arms 83 of the bail arecurved in order that they may fit around the body of the 1antern whenfolded down in order to make the device more compact for packing andtransportation.

The lens or glass may be colored, if desired, in order that the lanternmay be used for signaling purposes.

Vhile I have illustrated and described the rim 22 as being hinged to thelantern-body, it is obvious that it may be otherwise movably connectedthereto.

From the foregoing description it will be seen that on account of thelantern tapering from front to rear and having a reflector at the rearof the lamp of substantially the same diameter as the interior of thelantern-body a strong light will be projected forward and widelydiffused; also, that the light is effectually protected from strongcurrents of air and from water.

It will be understood that changes in the form,proportion, and minordetails of construction may be resorted to without departing from thespirit or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim is 1. In a lantern, aconico-cylindrical body having a downward tubular extension to form asupport, combined with a rim, carrying a lens or glass, movablyconnected to the front end of the said body, and a downwardly-extendingloop secured to the rim and forming another support for the lantern,substantially as described.

2. In a lantern, a conico-cylindrical body having a downward tubularextension provided with a flaring lower end, combined with a rim movablyconnected to the front end of the said body to leave a space betweenthem, said rim carrying a lens or glass, and a downwardly-extendingsupport rigidly secured to the rim and cooperating with the tubular eX-tension to support the lantern, substantially asdescribed. y

3. In a lantern, a conico-cylindrical body having a downward extensionto form a support, the wide end of said body being toward the front ofthe lantern, an illuminating device supported within the said body, anda reflector supported within the body in rear of the illuminatingdevice, combined with a rim movably connected to the front end of saidbody to leave a space between them, a downward extension on the rimtoform a support, a lens or glass carried by the rim, and a device todetachably lock the rim to said body, substantially as described.

4. In a lantern, a conico-cylindrical body the wide end of which istoward the front of the lantern, an illuminating device supported withinthe said body, and a reflectorsupported Within the body in rear of theilluminating device, combined with a rim hinged to the front end of saidbody to leave a space between them, shouldered stops secured to the bodyand projecting forwardly therefrom to engage said rim, a device todetachably lock the rim to said body, a lens or glass carried by saidrim, and downward extensions on the body and rim respectively, to formsupports for the lantern, substantially as described.

5. In a lantern, a conico-cylindrical body, the wide end of which istoward the front of the lantern, an illuminating device and a reflectorsupported within the body, combined with a rim hinged to the front endof said body to leave a space between them, a projection on the rim, aspring-catch secured to said body to engage said projection, and afinger-piece on the rim to be engaged by the finger when thespring-catch is engaged by the thumb, whereby the rim may be releasedand turned on its hinge, substantially as described.

In testimony that I claim the foregoing as my ownI have hereto axed mysignature in the presence of two witnesses.
